Plants need Vitamin C, too

Cornell University

Just as virtamin C protects humans and many animals from environmental stress, researchers at Boyce Thompson Institute for Plant Research Inc. at Cornell have found that mutant plants lacking vitamin C had shriveled leaves, and when grown in an ozone-contained environment, they were not able to cope with the environmental stress, and were hypersensitive to sulfur dioxide and ultraviolet B radiation.

Coevolution argues for preserving large land areas

Washington State University

By the late 1980s, Thompson had developed the geographic mosaic theory of coevolution, which argues that the long-term dynamics of coevolution occur over large geographic areas rather than within local populations. Much of his current research is directed toward evaluating this theory, his work on Greya moths and the plants they pollinate, for example.
